Furniture with my kid (grown) in mind stays fairly basic. And most of the time he just doesn't care about style, more his personality than interest. The big deal is having one chair that is his alone. A bed and dresser, plus a desk for computer stuff. The desk usually ends up in the livingroom or the dining area in apts. Not even sure if they use a dining table. And as other's mentioned less is more for the single guy. I really like the simple lines in the photos from the link. Once he gets into an apt. (which probably can't be painted), perhaps a shopping trip for linens, dishes together. He really needs to be part of this since it will be his place. If you could get him on a couple of the shopping sites, let him identify patterns/color in bedding, etc. May help to identify colors ahead of time. But for a guy I see gray/red with the couch. You are wonderful to do this for him. When my son got his first apartment it was Target for essentials, we did in in one shopping trip. I was able to give him furniture, but the one thing that has stayed with him through the years was the darn reclining leather chair with separate foot stool. I doubt if this will ever go away. Have two Army kids, but ask if your Marine wants a "Love ME" wall. If you know of anything he has pertaining to his enlisted time...pics, medals, uniform....this is their wall. They should be framed and created into a single area. I framed half dozen important photos and a deep frame for his top coat, added flag that says "Proud to have Served" with a number of other items of meaning to him which can't be framed sitting on a shelf below. Secretly, I think all soldiers go for this (they're the ones that named it). Thier admission to such usually happens when one least expects it. My oldest son is in Kuwait right now. Other served in Desert storm. Remember to thank the soldiers personally when you happen to see one. They don't hear it much and are truely thankful when a stranger hands them this small acknowledgement.

what a pretty place!! the fireplace, the shelving..oh my you gravitate to more modern glam-a bit-boho from what I read-so yes, your coffee table, TV console and, lastly, dining table are in a bit of a dissonance..a bit too rustic. also they have to be bigger. But not bulky visually, at the same time. (to the light, I'd get last unless I stumble upon something I love-because currently it kinda goes with everything. But you need to love your lights, no question. you can go any direction with the light here-the bones are handsome, the light is like jewelry that can be modern or taditional, stark or fancy) what's the budget? you have this great site there..not on the high street..it's huge..https://www.notonthehighstreet.com/home you also must have Anthropologie, right? you also have my favorite envy-https://www.rockettstgeorge.co.uk/ (the prices are allover) I'd look for a bit of metal. maybe a bit of stone or glass, a bit of woven texture to tie it all to the kitchen.. here are their side and coffee tables for example..I hesitate to make specific suggestion without knowing the budget https://www.rockettstgeorge.co.uk/furniture/tables/coffee-side-tables/show/48.html

I love it I've never been to Mexico yet. I seriously want to go someday. To Mexico City and some other cities..I don't recall the names right now. I saw them on TV..)) We've been to Costa Rica.. Nicaragua (Granada and several pueblos)..I'm not sure whether islands count? We stayed in some boutique hotel in St Lucia-everything was made by local crafstmen and artisans, one of the most memorable places in terms of design I've been to. Yes I'd gladly go there, and not once, if I'm fortunate to do so. I'd love to visit other countries too. I learned many new things there, and it's fascinating how architecture, design, colors inform of history etc In Granada for example no one's allowed to change their older house's architecture-it's one of the oldest cities in Northern America so they try to keep it as intact as possible. (was numerously rebuilt as it was often left in ruins by pirates etc) So in order to have fun and to change, they have a custom of repainting their facades every year. Usually on New Year's. The colors are pretty vibrant. So one year one can say "My house is a green one to the left side on street such and such"-but next year, it's pink or yellow or blue.. That's a bit of OT, probably Anyway, all that region is very interesting, and the more one sees and learns the more one wants to go there again.

So in other words you have a clean slate. The stone on your fireplace wall really isnt modern. Your kitchen cabinets are. I think a nice mix of warmth and industrial could work in the space. It looks like you have a fantastic lake? ocean? view. Think about a deep slate blue or navy blue for the wall. Id warm it up with a leather sofa but then bring it down with a concrete table. I would carry that mix, leather, metal, wood and concrete through. Art is subjective and I used it as a place holder but look how the art changes the whole look of the space in these renditions. The first takes it more rustic and the second more modern. Black and whites an entirely different direction.
